In the first installment of USA Today bestselling author Christi Caldwell's Sinful Brides series, a bookkeeper-turned-lady takes a gamble on a man she never meant to fall for. Lord Robert Dennington, the Marquess of Westfield, has long reveled in the freedom afforded him as the ducal heir. He knows he must someday do right by the Somerset line, but he's in no hurry to give up his carefree existence. Helena Banbury is a bookkeeper in a gentleman's gambling club, adept at analyzing numbers and accounts but helpless for lack of influence. She's never belonged among the nobility on the gaming hell floors, but neither does she feel completely herself among the men who run the Hell and Sin Club, despite the fact that they are family. The once-illiterate girl from the streets wants more than the gilded walls her protective cage can offer. When Robert mistakenly enters her chambers one night, Helena is forced out of her predictable life and thrust into the glittering world of Society. Will the charms of the marquess prove more perilous than any danger she ever knew on the streets?
